UNITE STATES HENR Y ll. FLEMING, OF HUDSON, NEvV YORK.

SASH-FASTENER.

SPECIFICATION forming part of Letters Patent No. 301,582, dated July 8,1884.

Application filed June 9, 1879.

T0 at whom it may concern.-

Be it known that I, H. LrsLn FLEMING, a

citizen of the United States, and now a resident of the city of Hudson,in the county of Columbia and State of New York, formerly a resident ofthe city of Elizabeth, in the county of Union and State of New Jersey,have invented a new and useful Improvement in Sash Latches or Fasteners,being intended as an improvement upon a device for which Letters Patentof theUnited StatesNo. 167,822 were issued to me September 21, 1875, asassignee of entire interest of Edward IV; Brettcll, also a resident ofthe latter-named city, county, and State, and of which said improvementthe following is a specification.

This improvement consists in substituting for the combination of a flatplate or bar extending from center to one side of sash, a sliding knob,and a V-shaped slide rigidly attached to and operating in connectionwith a spring-bolt, as in the device previously patented, thecombination of a centrallyafiixed recessed plate, a sliding knob, adetachable V-shaped slide, and a separately-adjustable spring-bolt, ashereinafter more fully de scribed, my object being to admit of readierattachment of latch to sash, and to avoid the mutilation of woodworkrequired when former device is used.

In the accompanying drawings, Figure l is an outer view of my improveddevice. Fig. Z'is an inner view, and Fig. 3 is a transverse Fig. 4. is asectional view of the lower part of a sash with the spring-bolt inplace.

Similar letters of reference in each indicate corresponding parts.

A represents the recessed plate, which may be centrally affixed to thelower rail of sash, and has formed therein a vertical slot to receiveshank of a sliding knob, 0, provided inside of said plate with the guideor follower D.

By 'E is represented the V-shaped slide slotted longitudinally, so as toreciprocate freely beneath plate, between same and sash upon shanks ofscrews used to secure said plate, or upon studs projecting inwardlytherefrom, which may be furnished for that purpose, said slide beingprovided with forked tongue 0, projecting inwardly at right angles withsame,

so as to engage with notched end of springbolt F, which extendslengthwise through said lower rail to side of sash.

G represents the usual pull-hook or liit, which may be attached directlyto plate A, or be secured independently to the sash beneath, as mostconvenient.

The operation of this improved latch is pre ,cisely similar to that ofdevice previously patented, so far as the mere mechanical movement ofpartsis concerned-via, the bolt being withdrawn through agency of knobO, follower D, and slide E, and returned automatically by action ofspring; but in the application of same it differs insomuch that the boltand spring may first be placed in position separately from other workingparts by insertion through small hole bored lengthwise in rail from oneside to center of sash, the V-shaped slide being next located byengagement of forked tongue with notched end of bolt, a recess beingformed in center of rail, communicating with above-named orifice toadmit of this connection. The recessed plate, having knob and followerpreviously attached, may then be placed over slide, so that follower maybear upon inclined face of same, and secured 'to sash by screws, theshanks of which pass through longitudinal slots in slide for the purposeaforesaid. By this method of attachment the objectionable gouging out ofsash necessitated with former device having flat plate, and rigidlyconnected with working parts, is avoided.

I do not claim, broadly or separately, recessed plates or thetongueconnection between slide and bolt; but

"What I do claim, and desire to secure by Letters Patent, as animprovement on said former device, previously patented to me as assigneeof Edward W. Brettell, as hereinbe fore stated, is

The combination of the centrally-affixed recessed plate A, sliding knoband follower C D, longitudinally-slotted detachable V-shaped slide E,provided with tongue 0, projecting inwardly at right angles with same,and the separately-adjustable notched spring-bolt F, all constructed andarranged substantially as shown and described, for the objects hereinset forth.
